如何在 Ubuntu 20.04 主機上安裝 WordPress (2021)

1. 建立 WordPress 資料庫
2. 安裝 Wordpress
3. 解決 佈景主題 外掛 無法安裝問題
4. 解決 永久連結 無法使用 問題
5. 手動 安裝 SSL 憑證

$ sudo tar xvzf latest-zh_TW.tar.gz

$ sudo cp -r wordpress/* /var/www/html

$ cd /var/www/html
$ sudo mv index.html _index.html

$ sudo vim /var/www/html/wp-config.php

解決方式 WordPress 繞過 FTP 自動升級外掛與佈景主題

$ sudo chown -R www-data:www-data /var/www/html/wp-content/

$ sudo chown -R www-data:www-data /var/www/html/wp-includes/

$ sudo vim /var/www/html/wp-config.php

define('FS_METHOD', 'direct');

$ sudo service apache2 restart

$ sudo service mysql restart

WordPress .htaccess 修改問題

$ sudo vim /etc/apache2/apache2.conf

<Directory />
        Options FollowSymLinks
        AllowOverride None
        Require all denied
</Directory>

<Directory /usr/share>
        AllowOverride None
        Require all granted
</Directory>

<Directory /var/www/>
        Options Indexes FollowSymLinks
        AllowOverride all
        Require all granted
</Directory>

$ sudo vim /var/www/html/.htaccess

$ sudo chmod 777 -R /var/www/html/.htaccess

$ sudo a2enmod rewrite

$ sudo service apache2 restart

$ sudo service mysql restart

1. 要有Public IP

2: Redirect - Make all requests redirect to secure HTTPS access. Choose this for
new sites, or if you're confident your site works on HTTPS. You can undo this

IMPORTANT NOTES:
 - Congratulations! Your certificate and chain have been saved at:
   /etc/letsencrypt/live/web.gcproy.ml/fullchain.pem
   Your key file has been saved at:
   /etc/letsencrypt/live/web.gcproy.ml/privkey.pem
   Your cert will expire on 2021-10-30. To obtain a new or tweaked
   version of this certificate in the future, simply run certbot again
   with the "certonly" option. To non-interactively renew *all* of
   your certificates, run "certbot renew"
 - Your account credentials have been saved in your Certbot
   configuration directory at /etc/letsencrypt. You should make a
   secure backup of this folder now. This configuration directory will
   also contain certificates and private keys obtained by Certbot so
   making regular backups of this folder is ideal.
